- Comfy & Ergonomic Support: Experience unparalleled comfort with our D-shaped chair cushion, featuring 2 inches of high-resilience foam. It offers exceptional durability and support, protecting your tailbone and alleviating pressure to promote muscle relaxation. Say goodbye to hard chair surfaces and constant posture adjustments during long hours of sitting. - Non-slip Bottom & Ties: The cushion is designed with a bottom covered in non-slip dots to prevent sliding. It also includes two removable 23.6-inch ties for added security, ensuring the cushion stays firmly in place. While the non-slip effect is effective initially, you can easily reattach the ties for extra stability after extended use. - Easy to Clean: Maintain your cushion's freshness with a removable zippered cover. Simply unzip, remove the cover, and wash by hand or machine on a cold setting. Air dry or tumble dry on low heat. Avoid ironing or bleaching the cushion, and do not wash the foam insert to preserve quality. - Attention to Details: Crafted from 250gm² polyester fabric, our cushion cover is breathable, skin-friendly, and built to last. The overlocking stitch design reinforces fabric edges to prevent fraying, enhancing durability. The horizontal zipper is discreetly wrapped to protect your furniture from scratches. - Ideal for Various Scenarios: Perfect for office chairs, dining chairs, or gaming setups, this cushion transforms any seating experience. Whether you're working long hours, enjoying a meal, or playing your favorite game, our cushion provides the support and comfort you need to stay focused and relaxed.
